GENERAL-SERVICE RAILWAY CAR.

Application filed August 29, 1922.

To all 107mm t m n.3/ Concern Be it known that l` YVILLIAM J. ROA, residing at Si'. Louis, State of Missouri, and being a` citizen of the United States, have in` rented certain new and useful Improvements in a General-Service Railway Car, of which the following` is a full, clear, and exact description, such will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof within the scope of the claims will occur to persons skilled in the art.

In said drawings:

Figure 1 is an elevation of a fragmentary portion of a dumping car showing a drop door held closed by the improved locking device;

Figure i2 is a transverse section through said car portion and drop door taken on line Q-Z of Figure 1 looking in the direction indicated bythe arrow` and showing the drop door positioned in a planebelow the tloorline of the car and held by the lockinke` device;

lFigure l is a horizontal sectional view through the car side above the door taken ou line 5;-3 of Figure l looking in the di,- rcction indicated by the arrow and showinflr u plan of the door loel'zing mechanism mounted at the car side;

Figure 4l is a vertical section. through one of the bearings securing the locking device to the car, and

Figure 5 is a view similar to Figure 2, but showing the door arranged Hush with the car floor.

My invention relates to that ela-ss of dumping cars in which the `floor comprises drop doors hinged to permit their free edges toi drop away from the car side and adapted to be severally raised bv hand.

l t is'an object of this inveiltitni to provide means for locking the several doors in their raised position, said means beingv adapted to severally release said doors.

A further object is to so arrange said locking mechanism as to permit the use of auxiliary devices to assist in the door raising operation.

In the drawings, 10 represents the center Serial No. 585,034.

sills of the car, 11 the car side,'12 the car floor, and 13 tjlesigl'nates one of the drop doors forming part of the floor area. ,lfhe doors 13 are shown hinged to the center sills l() with their free edges arranged near the car side. Each door is raised-b): hand and is locked in closed position and releaseil by means of a shaft 111- extending adjacent the free edge thereof andy mounted on the ear side above the door level.

rPhe shafts 14 are each provided intermediate their ends with a plurality of spaced stirrups 15 formed preferably by bending the shaft 14 as shown in Figure 1, the nnbent portions of the shaft being journalml in brackets 16 secured to the car side above the door. The stirrups 15 extend below the level of the door and are positioned to re ceive the door supporting and stiffener arms 17 secured to the underside of the door and extending beyond the free edge thereof and beyond the adjacent car side Due to the possible distortion of the door under conditions involving severe service the door may not completely close the discharge opening in the car floor r' IYilti` c' from the failure of one of the door Y arms 17 to properly seat. itself within adjacent stirrup Yl5 when the door is raised. 'flo insure complete closure thereof the stil-rups l5 are shaped as at 18 to provide ample room at one side of the door stillener arm l? to accommodate an auxiliary door liftingv hand bar (not. shown) for thrusting the respective side of the door to final closed po tion. `Each door, inwardly from the free edge thereof, is furnished with a loop piece 19 secured to the underside of the door between the door stilfeners 17 and between the stirrups 15 of the locking shaft to accommo* date the door lifting loar during the initial door raising operation,

Fixed to one extremity of the locking shaft lll is an operating handle il() held against movement within a keeper 2l seY cured to the car at a point loelow the door level. The keeper supports a latch plate S32 pivotally mounted to more `in a horizontal plane to a position into and out of the path of movement of operatinghandle Q0. Thelatch plate is `held in its handle lockingiiosition by pin 23 taking the keeper and latch plate.

To release a door7 locking pin is withdrawn and latch plate22 moved to a posi-- tion out of the path of handle 2O as indititl Cil

cated in broken lines in lligrure 3 and the handle moved outwardlyv and pintar-diy Vfrom their supporting' positions i the door as iiidicated in broken lines or this hn;-

ure whereupon the door will drop to dis charge its lading.

To raise a door all that is iiei;cssaryv is ,Q'raslii the door and litt saine to a positi high enoueh to permit door stillencr :rif-ins l? to enter their respective stirrups ing the auxiliary bar liereinbe to. it necessary. lllheu the doors haar raised to their tinal closed position. ha 2O ot the locking,` device will agfjain be or Within its keeper 2l., the latch plate will be returned to its handle ren4 inni poeitioi indicated in full lines in the distdir..- held against displacement by door. .shaft may be readily mounted upon and renioved from the car. The shailt Ajournal brackets i6 devised as shown .Jillgreatly facilitate the assembling' and dismantling operations. The brackets 1G comprise a base plate lixedly secured to the car by countersunk rivet 26 or they like. The base plate is provided with a shaft bearingportion 27 and a socket portion to accommodatel a complemental piece f2.9 having; a portion 30 adapted to interlock with the socket 2S on the vbase plate. Part 2S) has aishait bearing portion 81. bv means ol which and bearing;l

portion 2T olE the base plate. shalt 11.4 is sup-v ported, all ol said parts beiner held in operaH tive relation by a removable bolt 32 connectina` the ivboletothe car frame.

It will be notedthat each door forming part ot the car Afloor ot a dumping car is provided ivith a locking device having; no connection with any other door. or door locking devico=on said car. Each door is suingorted directly upon sba'lts Yimirnaled in a plane above the normal level ot' the door and eiurag'es said shajlit at points adjacent the sides o'l` said door and intermediate the shaft journal brackets 16. i

Although the Weigjbton the doors is concentrated on the stirrups oil. tbe lool-:infr shaft. tbe relative arrangement ot' the stirrups on. the shattand the shattjournal brackets 16 resultsin a further distribution ot the load to the'carover aspacecorresponding to the length ot saidlocking shaft.

What I claim is l. In a generalservice railway car having side walls and a i'loor, a plurality ot manu ally operable drop doors forming part ot the tloor arca oi the car and hinged with their Vl'ree edges adjacent the car sides, mania and sererally operable door supporting snails rotatably mounted on the side walls above the tree edges ot said doors when closed, said shal' 's being' operable independently to release said doors.

The combination comprising a general servie-e railway car havingv a manually operable drop door and a side wall, a supporting` shait on the side wall adjacent the free edge oi' said door shaped to provide spaced stirrup portions extending above and belenT the tree edge ot the door when raised, and shatt journal brackets on the car above said door and on opposite sides oit said stirrup portions.

ln a Lgeneral service railway car havin;` side walls and a plurality oit manuallyI and severally operable drop doors termino part oi the Vflow: between said Walls and hinged `with their 'free edges adjacent the car independently operable doorv support- "it yand a plurality et briickets on the 4l, T he combination comprising a general servire railrfay car having manually operable drop door and a side Wall, a locking u on the car Wall above the door-'when closed aid having; a plurality ot door supporting.' `tirrups intermediate its fls, and a piuralnv ot' shatt supportin,cY brackets on said wall on opposite sides ot said stirrups.

ina ;f.'ii.ei'al.service railway ear having i i and a plurality oil manually and severall' operable drop doors torn'nng part wall adiirent the tree edgre ot saidl door shaped to provide spaced stirrup portions 'intel'niediate.its ents and an operating,hanfdle at one exlrei'nitjf thereot, sba't't support-- inn' brackets on the car on opposite sides. ot said stirrup portions. and a keeperl on'the car adapted to receive said operating handle to prevent rotation of said shalt.

ln Witness whereof l have hereunto setv inf-,1 baud in the presence ot'itwo Witnesses.
